Overcoming Generator Failure for a Private University

During a routine Demand Response operation coordinated by the utility company, the university’s generator unexpectedly shut down approximately two hours into the run, posing risks to campus operations and safety.

Investigation revealed a catastrophic failure of the exciter stator/main alternator, disrupting the generator’s functionality and compromising its ability to support critical loads.

What did we do?

• Diagnostic Assessment: Our team promptly identified the exciter stator/main alternator as the root cause of the failure.
• Disassembly and Removal: The entire alternator assembly was carefully removed from the engine, minimizing disruption to the surrounding infrastructure.
• Professional Handling: Advanced lifting equipment ensured the safe transportation of the alternator off-site, maintaining its integrity.
• Comprehensive Rewind: Skilled technicians conducted a thorough rewind of the alternator windings, restoring operational capabilities.
• Rigging and Installation: The rebuilt alternator was meticulously rigged back into place, following industry standards and safety protocols.
• Testing and Validation: A rigorous four-hour load bank test was conducted to examine the alternator’s performance under simulated operational conditions, ensuring reliability and efficiency.

This case demonstrates our capability to address complex challenges efficiently, safeguarding critical infrastructure for our clients.
